Application led October 7, 1913. Serial No. 793,834.

T0 all whom it may concern Be it known that l, JOHNTTH, a Subj ect of the King of Hungary, residing atl Phoenixville, in the county of Chester and State of Pennsylvania, have invented certain new and useful. lmprovements in Railway-Crossing Gates, of which the following is a specilication.` Y

This invention relates to railway crossing gates. The object of the inventionis to provide a crossing gate vwhich will be operatedby an approaching train, in vsuch manner that ample time will be afforded a person approaching the crossing to enable him to stop his team in time to avoid danger.

A. further object is to provide a crossing gate which will be operated either by an approaching or a backing train,y or by two` trains going in opposite directions simul-` a part of this specification and in which like.

characters of reference indicate corresponding parts: Figure 1 is a view in perspective of a section of a two track railway equipped with the gato of the present invention. Fig. 2 is a view in side elevation, showing the manner in which the gates are actuated by an approaching train. Fig. 3 is a view in vertical longitudinal section through one pair of tracks, showing moreparticularly the connection between the engine actuated mechanism and the gates. Fig. 4l is a vertical transverse sectional view taken at the gates. Fig. 5 is a view in end elevation, partly in section, showing more particularly the manner in which the engine actuated mechanism is mounted in a box or casing disposed transversely of the tracks. 6 is a detail view in elevation, of the actuator for transmitting the power caused by the impact between the wheels of a locomotive or car to the gates.

Referring to the drawings, R designates two pairs of rails of the usual ordinary con struction and S, the sleepers or ties, and as these, parts may be of the usualy or any preferred construction, further description 4is deemed unnecessary.-

lt is designed that the tracks shall be .i

divided up into sections or blocks of any desired length, and at the end of each block and extending transversely of the tracks is a boxing or housing 1 which may be left open at its top or inclosed and may be constructed of any preferred material, such as wood, metal, or cement, as `may be found preferable. Secured to the iioor or base of each ofthe casings are three standards 2', 3,

and 4, the two standards 2 and 3 each carry-v ing avsingle journal box 5, while the intermediate standard, carries two journal boxes 6 and 7. rlhese journal boxes are engaged by two shafts 8 and 9, the outer ends of which project beyondthe standards 2 and 3, and. each has secured to it agrooved sheave 10 and 11. Rigidly secured on each of the shafts 3 and 9 are two disks 12 and 13, one

of which, in this instance, the disk 13 is shown in detail in Fig. (i.` Each of the disks has within its periphery a channel or groovelll inf whichis pivote'd at 15 a dog 16 having its lower end 17 rounded and its upper end provided with a right-angularly disposed lug or linger 18. Secured .to the inner wall of the channel is a spring19 that engages with. the dog adjacent to its upper end and is designed to act as a buffer to absorb the initial shock resulting from the contact of the wheel of a locomotive or car therewith. As clearly shown in Fig. 2, the dogs on the disks 12 normally occupy a vertical position .when the gates are raised, while the dogs onthe disks 13 are disposed at an angle of approximately 4:50 to the first-named dogs. In addition to forming a means for eifecting positive co-action betweenrthe dogs and the wheels of a locomotive or car, the lingers 18 also serve as stops to limit the downward throw of the dog as the linger will engage with the base of the rail when moved to the limit of its downward throw.

Arranged adjacent to the crossing C, and upon each side of the outer rails of the pair are two standards 20 that are bolted to a suitable base, not graphically illustrated, and are connected by a tubular brace 21 through which extends a shaft 22, journaled near its ends in the standards 2O and projecting beyond the same at each end, the -pro- 'ectino ortions havinO securedv to them` grooved sheaves 23, the arrangementen each side of the crossing being the same.y Air-v.v ranged adjacent to the crossing are four Standards or ,posts 24, the upper ends rof which are slotted at 251, and in each slotis pivoted a gate arm, designated respectively,

A, A, A2, A3, each being of suiicient length to lspan the crossing, and having at 1its lower end `a counter-weight 26, thus to'cau's'e lthe gate practically to be balanced so that but 'small power will be required 'to shift it'from a horizontal to a vertical position or vice versa. Each shaft or'pintle 127 ofthe 'gate arms carries Yon itsouter' end a kgroov'ed `sheave 28, and'passing around 'this sheave hand sheave 10 vand thence back'to the left v.hand sheave 10, from beneath.Vv The reverse of this arrangement of the cable on-the opposite side of the systemis lobserved. Now, in operation7 assumingthe parts to be in the position shown in Fig. l, land a'train appreaches yin the `direction of `thearrow shown v`thereon, "the forward `pilot wheel will contact withjthe dog on the inner `dish l2 of the right hand rails and partially `rotate theshaft 8, and through the `cable 30 rotate the left hand sheave 10 and right hand sheaveY 28 and vthus cause the gate arms A2 yand A3 fto .lower through the sheaves `28 .and ropes 29, 'the movement'of theshaft 8 at the 'opposite end of `the section to thatin which the vtrain is approaching being lrocked at the same time through its sheave l0 and the cable 301:0 bring the dog 18 on the disk 13 to position to be engaged by the forward pilotv wheel'of the locomotive when the engine leaves the block, thus to cause the `gates to` rise. This operation also `obtains when a train backs, or when two trains running in i opposite directions enter the block, in which case, thegates 4on both ysides of thetracl will be closed and opened independent of each rother.

The shock absorbingspring 19 is of great utilityv as without its employment, itvwould be [practically impossible to operate the structure as `the impact between `the pilot wheel yand the dog would almost inevitably result either in-a fracture ofthe latter or a ybreakage ofthe gates. V 4 is claimed "asiynew is:-

The combination with two fpairs Voff frail- 'Way-crossing 4gates adapted `to vbe' disposed "on `opposite sides of a doubletrack road,

reach 'of `said gates being adapted-2te mov'ein unison with a corresponding gate locatedat 'the opposite side of the road, andmeansV for opening and closing said gates by trains Amoving in either direction on each of `said tracks, comprising fa pair ofcontinuous par-- la'llel'shafts-extending across both tracks, and

supported in suitable -4bearings, fa' pair of posts at each side of the road,a sheave` i mounted `on 'eachl of said iposts, sheaves on the ends of fsai'd.parallel'shafts-ropes connecting the Ipost` `sheaves with .the .sheavesvon thefparallel shafts, a pair of horizontal shafts at each side of the crossing, each 'of' said shafts having mounted thereon'twecon-` tact-devices adapted to be operate'dby .a

each of said horizontal shafts, a rope conmoving train,f.a sheave on `the outer end of necting said ila'st-fnamed 'sheave with .the

sheave on the parallel shaft locatedvon lthe opposite side ofthe crossing, the said contact deviceson eachiof said horizontal shafts ybeing in angular relation 'to each other and so disposed that ya `train .moving in one direc# tion closes the gates at each'side of the road, i

through one of said contact devices before `reaching 'the crossing, and opens the Asame gates through the contact device on the opposite .side of the crossing;

In testimony whereof I aiiix my ysignature in .presence of two witnesses.
